Investigating supramolecular systems using Förster resonance energy transfer.

Chemical Society Reviews, 2018
Supramolecular systems have applications in areas as diverse as materials science, biochemistry, analytical chemistry, and nanomedicine. However, analyzing such systems can be challenging due to the wide range of time scales, binding strengths, distances,

Increasing the Stability of Deep Blue Phosphor‐Sensitized OLEDs Using the Polariton‐Enhanced Purcell Effect

Advanced Materials, EarlyView.
The polariton‐enhanced Purcell (PEP) effect is demonstrated to enhance the stability of the deep blue phosphor‐sensitized fluorescent (PSF) OLEDs by 3.1 X compared to PSF diodes lacking this effect. In addition, PSF‐OLEDs exhibit reduced EQE roll‐off and deep blue color emission.

Spatially Controlled 3‐D Multiplexed Aptamer Patterning in Hydrogels

Advanced Materials Interfaces, EarlyView.
A hydrogel platform based on norbornene‐functionalized polyvinyl alcohol enables high‐resolution, 3‐D multiplexed patterning of DNA aptamers via two‐photon polymerization. Two distinct aptamers are covalently immobilized with single micron‐scale precision across the x, y, and z dimensions.

Kinetic Subpopulations Detected by Single-molecule Spectroscopy: Fundamental Property of Functional Nucleic Acids or Experimental Artefact?

CHIMIA, 2013
Single-molecule spectroscopy allows the direct observation of conformational dynamics in individual biomolecules. Here, we describe how single-molecule Förster resonance energy transfer (smFRET) reveals heterogeneous kinetics in the EBS1*/IBS1 ...

Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging

Advanced Optical Materials, EarlyView.
By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...

Breaking Crystallinity for Optimal Dark Current: Nonfullerene Acceptor Dilution as a Strategy for High‐Performance Organic Photodetectors

Advanced Optical Materials, EarlyView.
Organic photodetectors (OPDs) based on polymer donor:non‐fullerene‐acceptor (NFA) bulk heterojunction blends offer strong light‐sensing potential, but require methods for optimization. This work demonstrates NFA dilution as an effective strategy to suppress dark current and enable state‐of‐the‐art performance by disrupting NFA crystallinity.

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters

Advanced Optical Materials, EarlyView.
Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.
